sanitary condition, it has for its principalobject to provide a sputumreceptacle which shall always appear clean and neat to persons using it.To this end we provide, in a vessel preferably contained in an outercasing or shell, a rocking sputum receiver which, dipping into adisinfecting solution which itcompletely obscures from view, is soconnected with a cover that the latter cannot be moved to or from theopen position without rocking the sputum receiver, so that sputumdeposited on the receiver is at once washed off on closing the cover,leav ing the receiver free or clean of sputum on the next subsequentopening of the cover. Preferably the receiver is heavier at one side ofits axis of rocking motion than at the other, so that it normally tendsto draw the cover to the closed position.

In the accompanying drawings, Figure 1 is a perspective view of theimproved sputum receptacle; Fig. 2 is a perspective view of the rockingreceiver, removed; Fig. 3 is a front to rear vertical sectional view ofthe device; Fig. 4 is a transverse sectional view showing the receiverin elevation; Fig. 5 is a perspective view of a fragment of the outercasing or shell; and Fig. 6 is a perspective view of the liquidcontaining vessel.

a is a rectangular box or casing provided with a cover Z) attached tothe casing by means of the hinges 0. This cover may be moved on itshinges by any convenient means, for instance, by means of the verticalrod This rod has a shoulder 2 near its lower end which rests on arearward projection f of the cover afforded by a plate suitably securedto the cover and having its rear end (directly affording saidprojection) turned up at an angle'of about 415. The lower end-portion itof the rod is reduced, and coiled about the same, between a shoulderiand a guiding bracket j which projects from the back of the box and inwhich said reduced portion of the rod slides,

is a spring k, normally holding the rod in its elevated position. Therod may be kept y from upward displacement by either of the pins Z and marranged therein, one below the projection f and the other below thebracket 7'.

Arranged in the casing a is a vessel '22- adapted to receive adisinfecting or other liquid 0 and having a flange g0 projecting cleararound the same at its topor mouth portion and seated on the edge ormouth portion of the box or casing a, which latter the vessel rathersnugly fits. A vertical groove 9 is cut in the inner surface of one ofthe end walls of the vessel 71., extending from the top ofsaid wallabout half way down the same; opposite the lower end of said slot thecorresponding end wallhas a. hole G" formed therein. The lower entlofthe slot and the hole aiford bearings for the trunnions s of the rockingreceiver a, the same being substantially in, the form of a partcylinder. in its normal position the curved surface of this receiver isimmersed in the liquid 0, it maintaining that position under the actionof gravity, because as shown, its trunnions s are near its upper or flatside 27- and are in a vertical plane cutting the receiver substantiallycentrally thereof. Projecting from its upper or fiat side is a handle uwhereby the receiver may be removed from the vessel, having tilted there :eiver sui'iiciently so that the right hand trunnion in Fig. 4 may bewithdrawn from its bearing. At one end the rocker t is provided with aprojecting screw 1) forming a pivot, the same appearing in Fig. 3 ineccentric relation to the trunnions s and slightly forward thereof. Tothe under side of the cover is attached a fitting 'w affording a pivoton. The pivots o'and w are connected by the link y, whose length is suchthat when the rocker is in its normal posi tion the cover stands closed.

[2 is a stop projecting inwardly from the rear wall of the vessel a andserving to limit the rocking motion of the receiver when the cover isopened.

W hen downward pressure is applied to the rod (5 to open. the coverasheretofore explained, the link 3 transmits rockingrnotion to thereceiver if, which may turn on its bearings until it is limited by thestop a. in that position its curved side is up, and,
